Description

TECHNICAL FIELD

[0001] The present application relates to the field of tobacco automation logistics, in particular to a device, system and method for automatic loading and unloading of cross-zone transferred tobacco bales. BACKGROUND

[0002] Due to the fact that a company has a one-zone primary tobacco making workshop, a one-zone primary tobacco packaging workshop, a two-zone secondary tobacco making workshop and a two-zone secondary tobacco packaging workshop, generally, the one-zone primary tobacco making workshop corresponds to the one-zone primary tobacco packaging workshop, and the two-zone secondary tobacco making workshop corresponds to the two-zone secondary tobacco packaging workshop. Subsequently, due to the change of production mode, a one-zone expansion production line is newly built. During the production process, the expanded tobacco is packed in a tobacco bale, and then the tobacco bale is forked onto a truck by a forklift, and then the tobacco bale is pulled to the two-zone by the truck, and then the tobacco bale is forked down by the forklift, and then it is re-stored for the two-zone secondary tobacco making workshop to blend and then supply to the two-zone secondary tobacco packaging workshop. Due to the fact that the tobacco bale is large in size and contains heavy tobacco, the forklift can only clamp one bale at a time, which is low in efficiency.

[0053] The technical solutions provided by the present application will be described in more detail below. Figures 1-9 The technical solutions provided by the present application will be described in more detail below.

[0054] The terms and phrases used in this document are explained.

[0055] Tobacco box, a special wooden box for packing tobacco, which has an RFID chip at the bottom and a tobacco box number on four sides. The tobacco box has a lid to keep the inside of the tobacco box closed, reduce the spread of tobacco aroma, and maintain the humidity of the tobacco in the tobacco box.

[0056] RFID chip: used to store information of the tobacco box (including tobacco box number, brand, version number, batch number, weight, etc.).

[0057] The inventor found that according to the production technology of the tobacco workshop, tobacco will be produced in different workshops, and these tobaccos will be packed and transported to another place for storage. In the related art, according to the requirements, a truck will be used to load the tobacco boxes produced in A workshop and transport them to B workshop; in B workshop, the tobacco boxes on the truck need to be unloaded and then stored. In the above process, a forklift is needed to unload the tobacco boxes one by one from the side, group by group, from the truck to the inbound conveying line, and then a forklift is needed to unload the tobacco boxes one by one from the inbound conveying line at the most downstream end to the place where they need to be stored. After the above unloading operation is completed, a forklift is then used to load the empty tobacco boxes one by one to the outbound conveying line, and then transport them from the outbound conveying line to the downstream end of the outbound conveying line, and then use a forklift to clamp and hold the empty tobacco boxes on the outbound conveying line to the truck.

[0058] The inventor further studies the prior art and finds that when the tobacco boxes are transferred between different areas, in addition to the time of truck transportation, the time of loading and unloading the truck, the time of transporting the tobacco boxes from the truck to the warehouse conveying line, and the time of carrying the tobacco boxes from the end of the warehouse conveying line to the storage position are all very long, which makes the efficiency of loading and unloading the truck very low. In order to solve the problem of low efficiency of loading and unloading the truck, the embodiment of the present application provides a device for automatically loading and unloading the tobacco boxes in cross-zone transfer, which can greatly improve the efficiency of loading and unloading the truck.

[0059] Referring to Figures 1-3 , the embodiment of the present application provides a device for automatically loading and unloading the tobacco boxes in cross-zone transfer, which comprises a transition conveying line 1, an out-of-warehouse conveying line 2 and an in-warehouse conveying line 3. The transition conveying line 1 is configured to be docked with the truck conveying line 71 located on the truck 7. The out-of-warehouse conveying line 2 is docked with the transition conveying line 1; the out-of-warehouse conveying line 2 comprises at least two out-of-warehouse platforms. The in-warehouse conveying line 3 is docked with the transition conveying line 1; the in-warehouse conveying line 3 comprises at least two in-warehouse platforms.

[0060] For ease of description, in some embodiments, the out-of-warehouse conveying line 2 comprises out-of-warehouse platforms A1-A11. Among them, the transition conveying line 1 comprises two, specifically the transition platforms C1 and C2 of the transition conveying line 1. The transition platforms C1 and C2 of the transition conveying line 1 are platforms that can realize bidirectional conveying, that is, the tobacco boxes 8 can be conveyed from the transition platform C1 to the transition platform C2 of the transition conveying line 1, or from the transition platform C2 to the transition platform C1 of the transition conveying line 1. The out-of-warehouse platform A1 is located at the most upstream and is farthest from the transition conveying line 1. The out-of-warehouse platform A11 is located at the most downstream and is closest to the transition conveying line 1. The in-warehouse conveying line 3 comprises in-warehouse platforms B1-B8. Among them, the in-warehouse platform B1 is located at the most upstream and is closest to the transition conveying line 1. The in-warehouse platform B8 is located at the most downstream and is farthest from the transition conveying line 1. The structure of the tobacco box 8 and the storage mode of the tobacco box 8 in the workshop are shown in Figure 5 、 Figure 6 .

[0061] The in-station B1 and the out-station A11 are located at different positions of the transition station C1 of the transition conveying line 1. Specifically, the transition conveying line 1 comprises a first conveying belt (not shown in the figure) conveying along a first conveying direction and a second conveying belt (not shown in the figure) conveying along a second conveying direction. The first conveying direction is parallel to the conveying direction of at least part of the out-station of the out-conveying line 2. The second conveying direction is parallel to the conveying direction of at least part of the in-station of the in-conveying line 3. The conveying direction of the in-station B1 is parallel to the first conveying direction S1 of the first conveying line of the transition station C1 of the transition conveying line 1, and the conveying direction of the out-station A11 is parallel to the second conveying direction S2 of the second conveying line of the transition station C1 of the transition conveying line 1. In some embodiments, the first conveying direction and the second conveying direction are perpendicular. In this way, the in-conveying line 3 and the out-conveying line 2 can avoid interfering with each other, and it is convenient to arrange the in-conveying line 3 and the out-conveying line 2, and it also makes the conveying between the transition station C1 and the in-station B1 and the out-station A11 more convenient, without the need for additional auxiliary components. In order to realize the transportation of the tobacco boxes 8 on each conveying line, the transition conveying line 1, the out-conveying line 2, the in-conveying line 3 and the truck conveying line 71 can be equipped with conveyors.

[0062] The transition conveying line 1 and the truck conveying line 71 on the truck 7 are connected, and the tobacco boxes 8 in the truck 7 can be directly conveyed from the truck conveying line 71 to the transition conveying line 1, and then directly conveyed from the transition conveying line 1 to the in-conveying line 3 without the intervention of a forklift or manual handling.

[0063] Direct conveying, also known as connection, means that the tobacco boxes 8 are conveyed from one conveying line to another conveying line without the need for manual or AGV automatic guided vehicles. Direct conveying of the transition conveying line 1 and the truck conveying line 71 means that the tobacco boxes 8 are directly conveyed from the transition conveying line 1 to the truck conveying line 71, which can also be understood as that the transition conveying line 1 and the truck conveying line 71 form a complete conveying line.

[0064] Referring to Figure 1, the transition conveying line 1 and the delivery conveying line 2 directly convey, which means that the tobacco boxes 8 are directly conveyed from the delivery conveying line 2 to the transition conveying line 1, and can also be understood as that the transition conveying line 1 and the delivery conveying line 2 form a complete conveying line. The transition conveying line 1 can include one or more platforms. The delivery conveying line 2 and the storage conveying line 3 each include a plurality of platforms. The transition conveying line 1 can include one or two transition platforms. The uppermost storage platform B1 of the storage conveying line 3 and the transition platform C1 of the transition conveying line 1 are connected, and the lowermost storage platform B8 of the storage conveying line 3 is an AGV storage platform. The AGV automatically guided vehicle takes the tobacco boxes 8 away from the AGV storage platform and places them in the designated storage position of the warehouse. The uppermost delivery platform A1 of the delivery conveying line 2 is a delivery platform, and the lowermost delivery platform A11 of the delivery conveying line 2 is connected to the transition conveying line 1.

[0065] The device for automatically loading and unloading the tobacco boxes of the cross-zone transported tobacco can realize two main operations: automatic delivery and automatic storage; can also realize two auxiliary operations: manual storage and manual delivery; and can also realize two operations: stop and emergency stop. Each of the above operations can be provided with a corresponding control button. Each button is arranged near the platform of the transition conveying line 1 closest to the truck 7, that is, near the transition platform C2 of the transition conveying line.

[0066] The truck conveying line 71 of the truck 7 can have the following structure: In order to more flexibly convey the position of each group of tobacco boxes 8, the truck conveying line 71 on the truck 7 is arranged with only one group of tobacco boxes 8 on each conveying line. For example, if the truck 7 can accommodate the length of 5 groups of tobacco boxes 8, five conveying machines need to be installed on the truck 7, and each conveying machine is provided with front and rear detection switches to detect whether the group of tobacco boxes 8 is in place. Each conveying machine can be independently forward or reverse. When the automatic delivery mode is selected, after the tobacco boxes 8 on the first conveying machine are conveyed to the conveying machine on the transition conveying line 1, and the two detection photoelectric switches of the first conveying machine do not detect the tobacco boxes 8, the second conveying machine then sends the tobacco boxes 8 to the first conveying machine, and then to the conveying machine on the transition conveying line 1, and so on. The storage is the opposite.

[0067] The automatic delivery is to convey the tobacco boxes 8, which can be filled with tobacco or empty, from the transition conveying line 1 to the truck 7 until the truck 7 is filled with the designated number of tobacco boxes 8, and then realize cross-zone conveying. When the automatic storage is conveyed from the truck 7 to the transition conveying line 1, the tobacco boxes 8, which can be filled with tobacco or empty, conveyed from the cross-zone are conveyed to the tobacco warehouse.

[0068] When abnormal phenomena occur, such as the tobacco boxes 8 being stuck and unable to be automatically conveyed, or some tobacco boxes 8 without information and needing to be conveyed across zones and unable to be automatically conveyed, the manual mode is used to convey the tobacco boxes 8 to realize the manual storage and manual delivery operations.

[0069] The installation position of the emergency stop button can be higher than those of other buttons, and in the event of danger such as hitting a person, the device can be stopped in an emergency, including stopping the operation of the conveyor, lifting of the conveyor, stopping the outbound, stopping the inbound, and stopping the conveyor on the truck 7.

[0070] The above technical solution produces tobacco according to the production plan and loads it into tobacco boxes 8. Two boxes are stacked together to quickly transport the tobacco boxes 8 to the truck 7 by buffering and automatic conveying, and the truck 7 is moved to the corresponding area. When the tobacco is stored, the information of the tobacco box 8 can be weighed and identified online and applied for storage, and the automatic storage of the tobacco box 8 and the empty box outbound mode are realized. Flexible production, rapid transfer, rapid storage and outbound, and reduced personnel input.

[0071] Referring to Figure 2 and Figure 7 In some embodiments, the device for automatically loading and unloading the tobacco box across the area also includes a transport vehicle 4 configured to place the tobacco box 8 to the starting platform of the outbound conveying line 2; the transport vehicle 4 is configured to fork one or two stacked tobacco boxes 8 at a time. The transport vehicle 4 is specifically an AGV automatic guided vehicle. The conveying height of the AGV automatic guided vehicle matches the conveying height of the inbound conveying line 3 and the outbound conveying line 2, so that the height of the tobacco box 8 does not need to be adjusted, and the tobacco box 8 can be directly transferred between the AGV automatic guided vehicle and the inbound conveying line 3 and the outbound conveying line 2.

[0072] In some embodiments, the device for automatically loading and unloading the tobacco box across the area also includes a detection system 5 and an abnormality processing platform 6, which is Figure 1 the platform D in the above. The detection system 5 is arranged adjacent to one of the platforms of the inbound conveying line 3 to detect whether the tobacco box 8 on the platform meets the requirements. The abnormality processing platform 6 and the platform are connected (specifically connected with the inbound platform B4) to receive the abnormal tobacco box 8 from the platform when the tobacco box 8 on the platform does not meet the requirements.

[0073] Referring to Figure 3 In some embodiments, the detection system 5 includes a photoelectric sensor 51, a weighing assembly 52, an RFID reader 53, a photographing system 54, and a controller.

[0074] The photoelectric sensor 51 is arranged adjacent to one of the storage platforms; the photoelectric sensor 51 is configured to detect the number of cigarette cases 8 located on the storage platform. The number of photoelectric sensors 51 is two, one of which is arranged at the height of one cigarette case 8, and the other is arranged at the height of two cigarette cases 8. By determining which photoelectric sensor 51 detects the signal, it can be determined whether it is the height of one cigarette case 8 or the height of two cigarette cases 8, so that it can be determined whether the number of cigarette cases 8 is one or two.

[0075] The weighing device can specifically adopt a structure that can not only transport the cigarette case 8 but also weigh the weight of the cigarette case 8 passing through. The weighing assembly 52 is installed on one of the storage platforms to detect the total weight of the cigarette cases 8 passing through the storage platform. The weight of one empty cigarette case is 200 kg, and the weight of two empty cigarette cases is 400 kg. The AGV automatic guided vehicle clamps two cigarette cases 8 at a time, as shown in FIG. 2, which can be either two empty cigarette cases or two full cigarette cases. If the weighing device weighs 400 kg, the group of cigarette cases 8 is empty; if the weighing device weighs more than 400 kg, the group of cigarette cases 8 is full. Figure 7 The weighing assembly 52 is installed on one of the storage platforms to detect the total weight of the cigarette cases 8 passing through the storage platform. The weight of one empty cigarette case is 200 kg, and the weight of two empty cigarette cases is 400 kg. The AGV automatic guided vehicle clamps two cigarette cases 8 at a time, as shown in FIG. 2, which can be either two empty cigarette cases or two full cigarette cases. If the weighing device weighs 400 kg, the group of cigarette cases 8 is empty; if the weighing device weighs more than 400 kg, the group of cigarette cases 8 is full.

[0076] The RFID reader 53 is installed on the storage platform to detect the information of the lower cigarette case 8 passing through the storage platform. The photographing system 54 is arranged adjacent to the storage platform; the photographing system 54 includes a camera to take a picture of the model of the upper cigarette case 8 passing through the storage platform. The controller is electrically connected with the weighing assembly 52, the RFID reader 53, and the photographing system 54 to determine whether each cigarette case 8 of the storage platform meets the storage condition according to the information transmitted by the weighing assembly 52, the RFID reader 53, and the photographing system 54. The photographing system 54 can take a picture synchronously during the operation of the weighing assembly 52; or take a picture before and after the weighing of the weighing assembly 52.

[0077] During the transportation of the cigarette case 8, the number of the group of cigarette cases 8 is determined by the photoelectric sensor 51 assembly, whether the cigarette case 8 is full or empty is determined by the weighing device, the information of the lower cigarette case 8 is read by the RFID reader 53, and the serial number of the upper cigarette case 8 is recognized by the photographing system 54. When the serial number, batch number, and version number of the two cigarette cases 8 are consistent, the conveyor continues to transport the two cigarette cases 8 to the AGV automatic guided vehicle storage platform at the end of the storage conveyor. If the serial number, batch number, and version number of the two cigarette cases 8 are inconsistent, the cigarette case 8 is transported to the abnormal processing platform 6 for manual verification and processing before being transported to the AGV automatic guided vehicle storage platform. If the information is inconsistent, it is easy to mix the brands, which may cause a large quality accident in the future.

[0078] When the AGV pickup platform detects that the tobacco box 8 is in place, it requests the WCS to enter the warehouse, and the WCS schedules the AGV automatic guided vehicle to clamp the tobacco box 8 at the AGV pickup platform and perform the entry task. The AGV clamps the tobacco box 8 to the designated location row and completes the task, and stores the information in the database. If the AGV clamped tobacco box 8 contains tobacco, the subsequent supply of the cigarette wrapping workshop calls for material to be discharged, and if the AGV clamped tobacco box 8 is empty, the subsequent supply of the silk making workshop is provided for emptying the tobacco.

[0079] Referring to Figure 1 and Figure 2 In some embodiments, the number of tobacco boxes 8 that can be stored by all the outbound stations of the outbound conveying line 2 is greater than or equal to the maximum number of tobacco boxes 8 that can be accommodated by the truck 7. In this way, the pre-storage of the tobacco boxes 8 can be achieved before the truck 7 arrives, so as to achieve rapid transplanting and rapid outbound after the truck 7 arrives, and less personnel investment.

[0080] Referring to Figure 1 and Figure 2 In some embodiments, the number of tobacco boxes 8 that can be stored by all the inbound stations of the inbound conveying line 3 is greater than or equal to the maximum number of tobacco boxes 8 that can be accommodated by the truck 7. In this way, the truck 7 can be loaded with tobacco boxes 8 in the shortest time after arriving, greatly improving the loading efficiency.

[0081] Referring to Figure 1 The embodiment of the present application also provides a system for automatically loading and unloading tobacco boxes for cross-zone transfer of tobacco, which comprises a truck 7 and the device for automatically loading and unloading tobacco boxes for cross-zone transfer of tobacco provided by any of the technical solutions of the present application. The truck 7 comprises a truck conveying line 71; and the truck conveying line 71 is connected to the transition conveying line 1 to realize the bidirectional conveying of the tobacco boxes 8 between the truck conveying line 71 and the transition conveying line 1.

[0082] The height of the transition conveying line 1 is the same as the height of the truck conveying line 71, so that the transition conveying line 1 and the truck conveying line 71 just fit together to form a complete conveying line, and the tobacco boxes 8 can be transferred between the transition conveying line 1 and the truck conveying line 71 without changing their own height.

[0083] Referring to Figure 9 The embodiment of the present application also provides a method for automatically loading and unloading tobacco boxes for cross-zone transfer of tobacco, which is realized by using the device for automatically loading and unloading tobacco boxes for cross-zone transfer of tobacco provided by any of the technical solutions of the present application. The method comprises the following steps:

[0084] Step S100, temporarily storing the tobacco boxes 8 to be loaded into the truck 7 on the outbound conveying line 2.

[0085] Specifically, the tobacco boxes 8 to be loaded into the truck 7 are temporarily stored on the outbound conveying line 2 at a position closest to the transition conveying line 1.

[0086] Taking the example that the outbound conveying line 2 includes 11 outbound stations, respectively denoted as A1, A2…A11. Among them, A1 is farthest from the transition conveying line 1, and A11 is closest to the transition conveying line 1. When the tobacco box 8 is outbound, it starts from the outbound station A1, passes through A2, A3…, and then is conveyed to the outbound station A11.

[0087] The number of temporarily stored tobacco boxes 8 is proportional to the number of tobacco boxes 8 that the truck 7 can load. For example, if the truck 7 is full of 10 tobacco boxes 8, then 5 outbound stations closest to the transition conveying line 1 can store tobacco boxes 8, and each outbound station stores 2 tobacco boxes 8. That is, the outbound stations A7 to A11 all store tobacco boxes 8.

[0088] Step S200, when the truck 7 arrives at the transition conveying line 1, the tobacco boxes 8 in the truck 7 are conveyed to the inbound conveying line 3 via the transition conveying line 1.

[0089] When the truck 7 meets the loading condition, the tobacco boxes 8 on the outbound station A11 are first conveyed to the transition conveying line 1, and then to the truck conveying line 71 of the truck 7. This process saves the time of clamping the tobacco boxes 8 by the AGV automatic guided vehicle to the outbound station A1, and then conveying to the outbound station A11.

[0090] Step S300, when it is detected that there is no tobacco box 8 on the transition conveying line 1, the outbound conveying line 2 is started to transport the tobacco boxes 8 on the outbound conveying line 2 to the truck conveying line 71 of the truck 7 via the transition conveying line 1.

[0091] In some embodiments, during the process of transporting the tobacco boxes 8 on the outbound conveying line 2 to the truck conveying line 71 of the truck 7 via the transition conveying line 1, the inbound conveying line 3 continues to convey to transport the tobacco boxes 8 on the inbound conveying line 3 to the warehouse via the inbound station.

[0092] In some embodiments, during the process that the inbound conveying line 3 continues to convey to transport the tobacco boxes 8 on the inbound conveying line 3 to the warehouse via the inbound station, the following steps are further included:

[0093] Step S400, detecting whether the tobacco boxes 8 on the inbound conveying line 3 meet the inbound condition.

[0094] The above-mentioned steps S300 and S400 can be performed simultaneously, or in the order shown in the front and back, or step S400 is performed first and then step S300 is performed. Figure 9

[0095] Step S500, if yes, the tobacco boxes 8 on the inbound conveying line 3 are transported to the warehouse via the inbound station.

[0096] ​Step S600, if not satisfied, the warehouse conveying line 3 on the tobacco box 8 via the warehouse station to the abnormal treatment station 6.

[0097] Some specific embodiments will be described below.

[0098] First, according to the plan issued by the production management department, the brand, region and quantity of the tobacco that needs to be transferred across the region are scheduled.

[0099] When the warehouse conveying line 2 has no tobacco box 8 at the warehouse station and is not malfunctioning, the warehouse station can send a warehouse application signal.

[0100] At the warehouse station, the information of the two tobacco boxes 8 clamped by the AGV is compared with the information stored in the database. If the information of the two tobacco boxes 8 clamped by the AGV read is consistent with the information stored in the database, task data is generated and transmitted to the database of the transfer destination warehouse area, and the warehouse conveying line 2 will transport the tobacco box 8 in sequence according to the generated task data to wait for the arrival of the truck 7 for transportation and loading. As long as the warehouse station has no tobacco box 8, the warehouse can be applied in time, and the tobacco box 8 can be temporarily stored on each warehouse station of the warehouse conveying line 2 before the arrival of the truck 7 or even after the arrival of the truck 7 but not completed unloading.

[0101] Specifically, after receiving the request task, the WCS (Warehouse Control System, abbreviated as WCS) requests the WMS (Warehouse Management System, abbreviated as WMS) to warehouse, and the system of the corresponding area sends the task to the AGV system, and the AGV moves the tobacco box 8 to the corresponding location of the tobacco box 8 storage area such as 101 row at a speed of clamping two tobacco boxes 8 or empty tobacco boxes at a time, and then moves the tobacco box 8 to the transfer warehouse station. After the AGV puts the tobacco box 8 on the warehouse station, the task information target address of the warehouse station is set to the empty station closest to the transition conveying line 1 of the warehouse conveying line 2. Then read the RFID information, read the RFID information of the lower tobacco box 8, and compare it with the information transmitted by the WCS. After the comparison information is consistent and successful, the box number is obtained, the warehouse request is confirmed, and then the tobacco box 8 is finally transported to the empty station closest to the transition conveying line 1.

[0102] The above process is the process of pre-storing the tobacco boxes 8, and by the above method, the tobacco boxes 8 can be stored on each empty station of the outbound conveying line 2. In this way, after each truck 7 arrives, if the truck 7 meets the loading conditions, the truck 7 can be loaded in the shortest time, so that the truck 7 can quickly transfer the tobacco boxes 8 to the corresponding area. Because the tobacco boxes 8 needed to be loaded into the truck 7 have been pre-stored on the outbound stations of the outbound conveying line 2. The so-called shortest time refers to that when the truck 7 meets the loading conditions, the tobacco boxes 8 can be immediately loaded into the truck 7. There is no need to wait or be placed to the first outbound station of the outbound conveying line 2, and there is no need to wait for the tobacco boxes 8 to be conveyed along the first outbound station to the outbound station closest to the truck 7. Because the tobacco boxes 8 have been pre-stored on the outbound stations of the outbound conveying line 2, the tobacco boxes can be stored on all the outbound stations A1-A11, or only be stored on part of the outbound stations A1-A11.

[0103] Secondly, after the truck 7 transfers the tobacco boxes 8 to the corresponding area and the related inbound and outbound stations, the conveying machine mode is changed to the automatic inbound mode. When the conveying machine on the truck 7 continues to convey the tobacco boxes 8 outward to the inbound and outbound stations, after the tobacco boxes 8 on the truck 7 are conveyed, the loading of the truck 7 is immediately performed.
